Samsung Galaxy Express GT-I8730 gets Android 5.0 update via CM12
The Samsung Galaxy Express does offer you some nice features for people looking for a cheap phone. It features a good 4.5-inch Super AMOLED display and a fast process to perform some quick task. It can run Jelly Bean officially but it should get updates. I do not think Samsung will pay attention to this phone for latest Android’s version. But XDA is doing so. There is Samsung Galaxy Express Android 5.0 update available unofficially on XDA as CyanogenMod 12.
This unofficial CM12 build is still in development stages but so many good features are working fine. You can experience bugs when you are paying anything using NFC or when you need the Camcorder (but, try other app, it might work). I do not recommend this custom firmware for a daily drive as it may not prove very stable. But if you just want to experience what Google has introduced on Lollipop 5.0 version, load this build and take a drive of delicious Android’s version.
Make sure you are on a latest version of a custom recovery like CWM and TWRP. Load both the zip package to your phone (ROM zip file and Gapps). Boot phone in recovery mode, take nandroid backup, then perform wipe and start installation. The first boot might take time, so wait.
